Front A-Arms, Black, ECX kits

One of the most demanded RPM A-arms recently is for the ECX Torment 2wd, Ruckus 2wd & Circuit 2wd. You wanted them; we made them! These new arms are everything you’ve come to expect from the leader in molded aftermarket A-arms. They’re stronger than stock, beefier to help survivability during those unexpected incidents and built to tighter tolerances, making critical suspension settings much easier to lock down.

Our A-arm design looks more aesthetically pleasing than stock, yet the design is more than just good looks. The angled leading and trailing edges are more aerodynamic and allow the A-arms to transition up and over objects much more easily than the blunt, flat-edged design of stock A-arms. We added huge bosses around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. We removed the tiny outer hinge pin locking screw as well, in favor of an in-line screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.

All RPM A-arms are designed from our incredibly tough blend of engineering grade nylons and are backed by our limited lifetime warranty against breakage. You can’t go wrong with RPM!

Heavy Duty Caster Blocks, ECX kits

Don’t let failed caster blocks ruin your day of fun. RPM Heavy Duty Caster Blocks for the ECX Boost, 2wd Circuit, 2wd Ruckus & 2wd Torment are designed to prevent downtime and keep you running! We redesigned the overall geometry of the caster block, increasing the thickness of the walls in key breakage areas by as much as 20%! We also integrated a strengthening rib down the center-line of our caster block to improve the overall rigidity, helping to reduce or completely eliminate the possibility of a hard hit yanking the king pin screws out of the spindle block.
Each RPM caster block is molded from our incredibly tough blend of engineering grade nylons for proven performance and durability. Like all RPM molded products, our Heavy Duty Caster Blocks are proudly made in the USA!

Tech Notes: RPM Heavy Duty Caster Blocks replace the stock caster blocks for both ECX #1090 and ECX #234000.

Oversized Front Spindle Blocks, ECX kits

RPM Oversized Front Spindle Blocks for the ECX Boost, Circuit 2wd, Ruckus 2wd & Torment 2wd are designed to solve several issues reported to us by RPM customers. The first and most obvious is bearing life. The stock 5x10mm bearings simply can’t handle the loads generated by these little monsters. RPM Oversized Front Spindle Blocks bump up the bearing size to 5x11mm bearings (not included). One millimeter in diameter may not seem like much but that little change nearly doubles all load and fatigue ratings over the stock bearing size! That means better performance, longer life and more time between maintenance periods.

Secondly, we designed our spindle blocks to outlast, outperform and outshine the stock versions. Each set of RPM spindle blocks is molded from our ultra-durable, world-renowned blend of engineering grade nylons to keep you rolling when everything else would have fallen apart! Our versions retain all stock geometry for a direct, no complications swap and are backed by our limited lifetime warranty against breakage. Bolt some American made muscle on your ride and you’ll get to the finish line every time!

Tech Notes: RPM Oversized Front Spindle Blocks replace stock ECX #1089 and the spindle blocks from ECX #234000. 5x11x4mm bearings are not included and are required for completion. Stock 10mm bearings will not work with RPM versions.

Rear A-Arms, Black, ECX kits

With the successful release of RPM front A-arms for the ECX Torment 2wd, Ruckus 2wd & Circuit 2wd. we now have rear A-arms available as well! They’re stronger than stock, beefier to help survivability during those unexpected incidents and built to tighter tolerances, making critical suspension settings much easier to lock down. They’re also lighter than stock by 4 grams each (or 8 grams in total for both rear A-arms). That means they’re 21% lighter than stock rear A-arms!

Similar to our front A-arms, our rear A-arms look better than stock, and functional in their design. The angled leading and trailing edges are more aerodynamic and allow the A-arms to transition up and over objects much more easily and helps reduce dirt build-up than the blunt, flat-edged design of stock A-arms. We added huge bosses around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. We removed the tiny outer hinge pin locking screw as well, in favor of an in-line retaining screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.

All RPM A-arms are backed by our limited lifetime warranty against breakage and molded from some of the best materials available. If you’re looking for performance, durability and piece of mind, look no further than RPM!

Servo Saver Eliminator Bellcrank, ECX kits

Are you tired of the wandering tendencies of your ECX Boost, 2wd Circuit, 2wd Ruckus or 2wd Torment? Does it feel like the servo never seems to center itself? Have you noticed the massive amounts of slop in the stock steering system? Or perhaps you noticed that when you reverse, the vehicle weaves or shakes badly. These are all symptoms of a weak servo-saver. The stock servo-saver doesn’t have the strength to retain a slop-free system, causing the steering system to shift without input from the driver.

The RPM Servo-Saver Eliminator Bellcrank for these vehicles fixes all of those problems and more! Our system completely eliminates the C-clip design of the stock system in favor of a solid servo-to-tie-rod system. Without the loose C-clip servo-saver in the middle like the stock system uses, the RPM system locks in the steering system with a solid arm from the servo linkage to the steering linkage for perfect tracking every time!

RPM Servo-Saver Eliminator Bellcranks are molded from our trademark blend of engineering grade nylons for worry-free performance and backed by our limited lifetime warranty against breakage.

Tech Notes: The RPM Servo-Saver Eliminator Bellcrank replaces the bellcranks and center-link from stock #ECX1028. This system eliminates any form of servo-saver from the steering linkage. Most stock servos can become damaged if another form of servo-saver is not used. RPM recommends servo-mounted servo-savers such as those offered by Kimbrough Racing Products if some form of servo protection is desired (some modifications to the chassis or skid plates may be necessary when installing an aftermarket servo saver). Each bellcrank system comes with ultra-tight tolerance Delrin bushings but is completely upgradeable to bearings (not included) to smooth out the steering even further. For reference, bearing sizes needed to upgrade would be 2 – 3x6x2.5mm, 2 – 5x8x2.5mm & 2 – 6x10x3mm.
